Gunman’s brain to be studied
Scientists plan a microscopic examination of the Las Vegas shooter’s brain.
LAS VEGAS — Scientists are preparing to do a microscopic study of the Las Vegas gunman’s brain, but whatever they find, if anything, likely won’t be what led him to kill 58 people in the worst mass shooting in modern U.S. history, experts said.
Stephen Paddock’s brain is being sent to Stanford University for a monthslong examination after a visual inspection during an autopsy found no abnormalities, Las Vegas authorities said.
Doctors will perform multiple forensic analyses, including an exam of the 64-year-old’s brain tissue to find any possible neurological problems.
Stanford has been instructed to spare no expense for the work, The New York Times reported. The brain will be further dissected to determine if Paddock suffered from health problems such as strokes, blood vessel diseases, tumors, some types of epilepsy, multiple sclerosis, degenerative disorders, physical trauma and infections.
Dr. Hannes Vogel, Stanford University Medical Center’s director of neuropathology, would not discuss the procedure and referred questions to officials in Clark County, where Las Vegas is located. They also refused to provide details.
Vogel told The New York Times that he will leave nothing overlooked to put to rest much of the speculation on Paddock’s health as investigators struggle to identify a motive for the shooting.
The examination will come about a month after Paddock unleashed more than a thousand bullets through the windows of a 32nd floor suite at the Mandalay Bay casino-hotel into a crowd attending an outdoor country music festival. After killing 58 people and wounding hundreds more, Paddock took his own life with a shot through his mouth, police say.
Investigators remain frustrated by a lack of clues that would point to his motive. Authorities have resorted to putting up billboards in southern Nevada seeking tips.
If a disease is found from the brain study, experts say it would be false science to conclude it caused or perhaps even contributed to the massacre, even if that explanation would ease the minds of investigators and the world at large.
“There’s a difference between association and causality, and just because you have anything, doesn’t mean it does anything,” said Brian Peterson, president of the National Association of Medical Examiners and chief coroner of Wisconsin’s Milwaukee County.
The microscopic study is not a standard practice but is regularly used as needed. Families sometimes request such a detailed examination to better understand their own genetic risks. Peterson said it’s also common in high-profile cases such as Paddock’s.
Douglas Fields, a neuroscientist who studies the rage circuit in brain systems, said horribly violent events, such as mass shootings and terrorism, rarely involve actual brain abnormalities but can be triggered by psychiatric problems.
Perpetrators often are suicidal psychopaths who are motivated to commit heinous crimes because they have internalized their isolation and anti-social behavior as an existential threat for themselves, he said.
“When police look for motive, it’s kind of misplaced in cases like this because they appear to be crimes of rage. There’s no motive for crimes of rage. It’s a crime of passion,” Fields said.
One such case involved the University of Texas shooter Charles Whitman, who fatally shot 13 people in 1966 from a clock tower on the Austin campus. Whitman was found to have a pecan-size tumor in his brain, though the suggestion that it caused his rampage is still debated decades later.
Dr. Paul S. Appelbaum, a psychiatry expert at Columbia University, said the brain study might yield something even tangential that can be passed on to the public, such as awareness for psychological disorders or brain diseases.
“Are we ever going to know for certain what caused his brain to do that?” Appelbaum asked. “Probably not from a neuropathological examination, but it’s not unreasonable to ask and see whether it might contribute to our understanding of what occurred.”
